MixedThe Boston GlobeWhen Dyer’s insights gain altitude, they are transcendent, reminding us that every square inch of the planet shimmers with the magnetism of its former life and former meaning. And yet, even as that awareness rises in him, it’s clear that Dyer is not someone comfortable in an empty world, and he connects most easily to the sublime through the man-made, like the eerie Lightning Field, and as the installation’s artificial magic gathers steam in his consciousness, the power of the landscape itself, and its existence before civilization and art, seems to dwindle. By the time you finish this collection, the answer to the question — What is Geoff Dyer searching for? — comes not directly but by default. To be alive, I suppose, is the answer. To make sure his world is as big as he can get it and to make sure that his mind keeps apace of that expansion. A worthy enough mandate for a guy just passing through, as are we all.
